Title: Chemical pH meter
Inventor: VOIPIO VILLE
IPC: G01N21/78
Filed: 1999-06-16
Abstract: The chemical pH meter has an indicator with a layer on a glass plate, with varying color viewed as reflected light. An indicator is applied to one face of glass plate and covered by one or more layers of reflective, porous, material. The reflective material presents a rough surface to the indicator so that the reflected light is diffused. The cover can be a single material or two different materials with a rough interface. Alternatively a dielectric mirror is formed on the indicator by alternating layers of two different materials with widely different refractive indices, arranged so that the material with the high index is next to the indicator. Although pH measurement is a primary function, other properties, such as concentration, that effect a color change on an indicator, can be measured.

Title: Configuration of functional characteristics of audio-instrument, especially of electronic hearing aid
Inventor: MUELLER STEFAN
IPC: H04R25/00
Filed: 1999-10-14
Abstract: The method involves providing the instrument with an IC which can be differently configured with respect to its functional characteristics, and providing a configuration upgrade information in a suitable data memory. The IC of the instrument is configured during production, in such way, that the instrument comprises in a base version solely the least possible characteristics, and the instrument is sold at a basic price, especially to resellers.  The configuration upgrade information is loaded during production on a separate data carrier which is sold, especially to resellers, at a price dependent on the kind and amount of the contained configuration upgrade information. The configuration upgrade information may be transmitted in an on-line operation from a software memory of the maker to a temporary memory of a programming station of the reseller. The IC is entered in the programming station, and is upgraded to a customised higher functionality level. A selection information is, if necessary, read and stored on the data carrier, in such way, that the entire, or part of the contained software package, can not be read a further time, and be programmed into the IC. The upgraded instrument is distributed and billed according to the additional functional characteristics.
